One of the Mysteries at the Center of Our Galaxy Has Been Solved!

While studies on dark matter, one of the biggest mysteries of space, continue rapidly, new news has come from the scientific world today. Nature Astronomy Scientists have found an explanation for the mystery about Sagittarius, the satellite galaxy inside the Milky Way Galaxy, according to research published in the journal Cell.

The new discovery confirms a theory that astronomers have long supported about dark matter. providing evidence to the contrary was quality. So what was this theory? What does this discovery tell the world of science? Let’s look at the details.

Let’s first explain what the mystery is:

The center of our galaxy reveals a pair of gamma radiation bubbles represented by the purple segments in the image above. Although this phenomenon was discovered ten years ago, its origin remains a mystery. These radiation bubblesFermi bubbles‘ was called.

If this is one of the brightest areas in the Southern part of the bubbles ‘Fermi cocoonwas called ‘. This structure can be seen zoomed in on the image above. The structure in question is a phenomenon that once lived in our galaxy. the result of the supernova event was believed.

That structure was actually a result of the radiation emitted by the satellite galaxy:

By examining the data obtained from the GAIA and Fermi space telescopes, scientists were able to identify the source of the structure we mentioned above. Satellite galaxy of the source of the promise Fermi cocoon originates from Sagittarius announced.

So what is the source of Sagittarius’ gamma-ray radiation?

Gamma-ray radiation from the galaxy was thought to have several possible causes, as Sagittarius did not contain gas or stars. It is believed to be one of the reasons millisecond pulsars are set to qualify as the biggest explanation with the new discovery. started. On the other hand, this evidence also contradicted the other theory that radiation originates from dark matter.

What is a millisecond pulsar?

Pulsars are described as the core and ‘heart’ of the celestial structures they are in and are neutron stars that send radio waves into space like heartbeats. Millisecond pulsars, on the other hand, are the name given to pulsars with rotational periods in the range of about 1-10 milliseconds. The widely accepted theory for the origin of these pulsars is that they were accelerated neutron stars by accumulating matter from very rapidly spinning near-binary binary stars.
